English term

present 2 days to months

English Medical Medical (general) transfusion
Delayed hemolytic transfusion reactions occur because of incompability of minor antigens and are characterized by extravascular hemolysis. They present 2 days to months after transfusion.

does it mean " appear after 2 days or even after a few months" or " are present for two days to a few months = last this long " ?
Thank you in advance

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.

How to tell the difference between "easy" and "pro" questions:

An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)

A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).

Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.

When deciding between easy and pro, err on the side of pro. Most questions will be pro.

* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

Discussion

R.S. (asker) Jun 20, 2010:
Thank you, Tony for confirming my interpretation. What confused me was voting my question non-pro by the user who understands it as "within two days" in his/her comment. After all, anyone who votes non-pro seems to send the following message "the answer is obvious, my confidence level is 5".
Tony M Jun 17, 2010:
My understanding (not a medical expert, though!) is that it is 'no earlier than 2 days' — to me, the clear implication is that you must wait at least 2 days before expecting to see these signs, but that they may even take a lot longer than that to appear.
R.S. (asker) Jun 17, 2010:
one more question who is right about the meaning of "two days" here:
1)Fahd Hassanein who says "no earlier than two days" or
2)ildiko who says "as early as within two days"?

"within two days" implies even the first few hours after transfusion, doesn't it?
B D Finch Jun 16, 2010:
Two Two should be written in full and appears to indicate the shortest period of time that elapses before reactions are observable. Several months, as the number of months is not specified.
Tina Vonhof (X) Jun 16, 2010:
I would say a few months or several months.
R.S. (asker) Jun 16, 2010:
how many months? I don't know about "2", it's written aa a digit, not word in my text.
I have a question about the months: how many does the author mean? : two? a few? I can't leave it blank before "months" as it would sound awkward in my native language.
Tina Vonhof (X) Jun 16, 2010:
Error? It sounds to me as if the number 2 is an error. It would be much more logical to say "appear after days or even after a few months".

appear after 2 days to as long as months

They appear no earlier than 2 days and may still appear for as long as months.

The term cannot mean (in this specialized field) that the reactions occur for two days. "They present 2 days to months AFTER transfusion." The word "present" is actually where the problem lies for non-medical professionals. It means "show up" or "appear" as Tony explained in his comment. 2 days is the minimum period before which no reactions appear and they may appear later than that period for as long as months.

Thanks!
neutral British Diana : This does not really solve the ambiguity. Which of the alternatives do you support?

Thanks! You may review the question again and Tony M's comment with his agreement.
agree Tony M : 'to present' means 'to show up' or 'to appear', and is not the same as 'to be present'

become observable two days or even months after transfusion

My understanding of "present" here is that it means that the symptom becomes observable. I believe that the time span given is not the duration of the symptom's observability, but the time when it might first become observable.

agree British Diana : This is the explanation I was looking for!

they present themselves

A google search on "they present themselves" + symptoms has many interesting examples.

Here's one:

Regular testing for colon polyps and removing them when they present themselves is vital.

agree Tony M : Poor English, but sadly does occur!

neutral B D Finch : I have often come across "to present" used as in the question i.e. as an intransitive verb. I think it is quite standard medical language.
